[PATCH 03/13] ALSA: usb-audio: scarlett_gen2: Fix -Wformat-truncation warning

[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



The recent enablement of -Wformat-truncation leads to a false-positive
warning for mixer_scarlett_gen2.c.

For suppressing the warning, replace snprintf() with scnprintf().
As stated in the above, truncation doesn't matter.
